This article examines the reasons for the observed discrepancy between worker's actual and required levels of schooling and the resulting economic effects in wage and labor mobility using KRIVET's Graduates Economic Activities Survey in 2005. Overeducated workers in Korea are estimated to be 10.1%-20.7% among junior college graduates and 18.8% among university graduates for their first job according to job analysis method and worker's self-assessment method each. The effects of school quality-measured by the student/teacher ratio, school building area/student ratio-on the overeducation of their graduates are found to be mostly insignificant not only junior colleges but also universities. This founding implies that the increase of education investment from schools does not acquire any recognition from the labor market. Also, the effects of overeducation and school quality on wages are found to be insignificant and job mobility has little effects on improving overeducated workers' job match.

This study intended to present strategies and implications for attracting new students and customized education to university officials through research on the participation of workers' academic aspirations in university education. Thus, variables were derived by analyzing prior data, and causal settings between variables and questionnaires were developed. Subject to the survey, 331 workers interested in participating in university education were collected through interpersonal interviews. The collected data were dataized, and reliability and feasibility verification and frequency analysis were conducted. Finally, we validate the fit of the structural equation model and the causal relationship for each concept. Therefore, the results of the validation show the following implications. First, university officials should be motivated by a mentor and mentee system with experienced people who have switched to a suitable vocational group through university education. It will also be necessary to develop and disseminate programs so that they can continue to develop themselves for the future. To this end, it will be necessary to help them understand their aptitude and strengths through consultation with experts. Second, university officials should strengthen public relations so that prospective students can know the cases and information of the job transformation of the admitted workers through recommendations. It will also be necessary to develop university education programs that can self-develop, accept various ideas through "public contest", and provide accurate information about university education to workers through re-processing. Third, university officials should provide workers with a program that allows them to catch two rabbits: job transformation and self-improvement through university education. In other words, it is necessary to stimulate the motivation of workers by providing various information such as visiting advanced overseas companies, obtaining various certificates, moving between departments of blue-collar and white-collar, and transfer opportunities. Fourth, university officials should actively promote university education programs related to this by participating in university education and receiving systematic education and the flow of social environment. Finally, university officials will need to consult and promote workers so that they can self-develop when they participate in college education, and they will have to figure out what they need for self-development through demand surveys and analysis.

This study uses the 12-21st waves of KLIPS to estimate the effect of the increase in the minimum wage on the individual's labor market transition through a multinomial logit. In particular, we examine whether there was an additional effect of the rapid increase in the minimum wage in 2018. The main results of this study are as follows. First, the increase in the minimum wage in Korea is found to have increased the probability of becoming unemployed for both wage workers and self-employed, but there is no additional impact found from the 2018 minimum wage increase. Second, the increase in the minimum wage is found to increase the likelihood of the self-employed entering into wage workers, especially temporary and daily workers. Third, we have found that the increase in the minimum wage in 2018 adversely affected self-employed people with high school education, and significantly lowered young wage workers entering into self-employed. Our results suggest that the recent increase in the minimum wage may be responsible for declining self-employment rate in Korea, and may have a negative effect on the quality of employment because the increase in minimum wage can lead to an increase in temporary and daily wage workers.

Using the 1st to 13th rounds of occupational history data of the Korea Employment Information Service's Youth Panel (YP2007), this study explores the trends and characteristics of the youth labor market in Seoul. We further empirically investigated the job duration and wage determinants of youth employed in Seoul. The results confirm that workers who have a higher income and a higher consistency with their majors are less likely to leave. In addition, we find that workers in full-time, householders, or labor unions have a higher income if they are men and work in large companies. In particular, compared to the reference group (appropriate academic background, appropriate skill), mismatches in the lack of education and skill showed a wage increase effect of 4.9% and 5.5%, respectively. For the major consistency, the wage of the matched major group is 3.8% higher than the non-matched major group.

This paper first constructs an occupation code-skill match for the Korean labor market by following Autor-Dorn classification on the tasks framework. Over the last 34 years, middle-skill jobs have vanished enormously, while high-skill and low-skill jobs have both increased. Also, jobs have polarized more rapidly in recessions and changed uniquely by pushing old workers into middle and low-skilled jobs and the inter-sector reallocation of workers. Furthermore, jobless recoveries in the recent business cycle could have been alleviated considerably if job polarization had been mitigated.

The purposes of the present study were: (1) to investigate aeromedical dissorders prevalent among ROK air force pilots and (2) to evaluate their detrimental effects on flight performance. The study examined the eight flight-induced disorders primarily responsible for permanent grounding and flying restrictions. According to the survey of 600 randomly selected pilots, 80.2% of the respondents have experienced low back pain, which was 20% higher than the lifetime prevalence in Swedish male workers. Bradyacusia ranked second (56.0%) resulting from continuous exposure to high aircraft noise. The cardiovascular disorders, the most common cause for permanent grounding of Canadian forces pilots, were found in 16.0% of the Korean pilots. Due to the high prevalence of the disorders, in 1993 the Korean pilots received medical treatments 10 times as many as factory workdes. Compared to the flight performance of Israeli and British pilots in wars, the flight performance of the Korean pilots was found to be inferior. Such poor performance can be attributable to the high incidence rates of disorders. Statistical analyses revealed that the aeromedical disorders were related to personal variables such as age, flight career- related factors, and fatigue. Cigarette smoking and drinking habit contributed to worsening back pain, barotitis media, and pulmonary disorders. More comprehensive research was recommended to identify health hazards, combined with intervention to minimize disorders that could lead to early termination of flight careers or excessive loss of flight time. This study further suggests that aeromedical institutions in Korean air force should be fostered more professionally and financially.

프로그래머블 컨트롤러(PC)라고 하는 제어장치가 1970년대말부터 급격하게 사용되기 시작된 것은 주지하는 바와 같다. 그후 어느 조사에 의하면 PC의 연간 신장률이 $30\~40\%$나 됐다고 한다. 본고는 앞으로 1년간에 걸쳐 (1) 종래 전자 릴레이 시퀀스 제어기술 영역의 업무에 종사해 왔지만 PC와 접하지 않으면 안되게 된 사람과 (2) 새로 학교나 직업훈련소를 나와 앞으로 PC를 취급하는 직장에 종사하게 된 사람들을 대상으로 연재를 시작하는 것이므로 시퀀스 제어의 동작, 회로, 회로도를 보는 방법, 그리는 방법에 대해서 일단의 지식과 경험이 있어야 하는 것이 전제조건이 된다. 본 연재는 종래의 시퀀스 제어회로를 PC의 프로그램으로 표현하려면 어떻게 생각하면 되는가를 중심으로 완결된 프로그램을 들어 기술한다. 즉, 지금까지 전선으로 릴레이간을 배선하여 제어회로를 작성하고 있던 것을 PC의 프로그램으로 만드는(이것을 소프트 와이어드라고도 한다) 방법이 설명되고 있다. PC 프로그램 작성은 용이성이 필요 조건이 된다. 이를 위해 본고에서는 명령의 수를 제한하고 프로그램의 논리구조가 명확해지는 방법을 사용하였다. 본 연재는 앞에서 언급한 바와 같이 소형 PC를 릴레이 대신 사용하는 방법에 대해서 기술하는 것으로서, 시퀀스 제어계의 설계에 관해서는 취급하고 있지 않다. 그것은 별차원의 것이기 때문이다. 그러나 PC로 시퀀스 제어회로를 간단히 작성하게 되면 다음은 회로를 어떻게 해서 만드는가 또는 회로를 만드는 것이 아니고 기계의 움직임을 그대로 표현하고 그것을 프로그램으로 하는 것같은 이른바 설계법으로 PC의 과제가 이동해 하는 것은 확실하다. 소프트 와이어드화의 힘이 붙으면 다음은 시퀀스 제어계의 동작 표현법, 설계법으로 흥미가 옮겨 가게 된다. 본고가 이것으로의 교량역할이 된다면 다행이겠다.

The purpose of this study was to identify the characteristics of college graduates who obtain qualifications, and to check the economic and ineffectiveness of qualifications through the analysis of employment and job relevance according to their school area. For the main research, the "2016 Graduates Occupational Mobility Survey (GOMS)" data was used to perform basic statistics and logistic regression analysis using SPSS 25. This study reaffirmed the effectiveness of employment as stated in the preceding study, and in particular, the qualification of non-Seoul area colleges students had some positive effects on employment and job compatibility. In conclusion, the effectiveness of qualifications according to individual attributes and location of school may differ, but it suggests that proper qualification encouragement and acquisition support can help the employment and job convergence of college graduates.

2000년 말 현재 이동전화기가입자 중 약 $91\%$가 무선 인터넷 가능 단말기를 보유하고 있다. 그러나 이러한 단말기의 보급에도 불구하고 무선인터넷 서비스 이용률은 매우 저조란 실적이다. 여러 가지 이유가 있겠지만 그 중의 하나로서 본 연구는 소비자 특성인 무선인터넷 이용에 미치는 영향에 초점을 맞추었다. 이를 위해 본 연구는 다음과 같은 연구 문제를 설정하였다. 1)무선인터넷 이용에 영향을 미치는 소비자의 인구통계학적 특설변수는 무엇인가? 2) 무선인터넷 단말보유자는 라이프스타일에 따라 어떻게 유형화되는가? 3) 무선인터넷 단말 보유자의 유형별 특성은 무엇이며 무선인터넷 인용에 있어서 어떠한 차이가 존재하는가? 이 문제에 대한 답을 구하기 위해 본 연구에서는 전국의 무선인터넷 단말기 보유자 1500면을 대상으로 일대일 면접방식으로 설문을 실시하였다. 분석결과 인구통계학적인 변수 중에서는 연령과 직업, 결혼여부, 학생, 개인용돈 등인 무선인터넷 이용에 영향을 미치는 것으로 나타났다. 분석결과를 종합적으로 요약해 볼 때 무선인터넷 서비스를 이용하고 있는 소비자들의 인구통계학적인 특징은 학생 중심의 젊은층이었다. 한편 성별이나 가족의 월수입은 무선인터넷 이용여부에 통계적으로 유의란 영향을 미치지 않는 것으로 나타났다. 또한 라이프스타일에 따라 무선인터넷 가능 단말 보유자 집단을 세분화해 본 결과 선구자형, 실용성추구형, 보수추구형, 자기과시형 둥 네 유형으로 분류할 수 있었으며, 집단 간에 무선인터넷 이용에 있어서 유의한 차이가 있음이 나타났다.
